Mercury Plant Controller Installation Guide Note 2: Several probe types are available, see Probe Type Note 3: The Status LED is not present on older variants of the Plant controller hardware. If the status LED is present and the Plant controller software is V1.7 or greater then Analogue inputs 1 to 3 are configurable either as a 4-20mA input or a 0-10Vdc input. If the above criteria is not met then Analogue inputs 1 to 3 are configurable as 420mA inputs only. In software version 2.
Mercury Plant Controller Installation Guide Universal IO Setting up from controller display, navigate to the screen “Uni” and select from the following table for U-01 to U-08. This selects what the Universal IO (U-01 to U-08) can be set for. NOTE: UniIO U-01 to U-03 can only be set as Inputs, UniIO U-04 and U-05 can only be set for Outputs and UniIO U-06 to U-08 are seen in settings but are not present on the controller hardware and are for future development.

Mercury Plant Controller Installation Guide * Span and Offset allows for the full range of the transducer to be used by the controller. Span is the full range of the transducer Offset is the value below zero. Note. The controller uses absolute pressure; if gauge pressure is required, add +1 Bar to the offset value. Example: Danfoss AKS 33 with range: -1 bar to 12 bar Span would be 190 (13 bar) Offset would be -15 (-1 bar) If only transducer input 1 in use please see Note 10 also.

Mercury Plant Controller Installation Guide To reset the run proof for any stage, after maintenance, and return a compressor back into the control strategy use the menu item Override. The override option is used to manually turn on the compressor output. If the proof signal is returned within the allotted time delay the compressor is allocated back into the control strategy; if the proof isn’t returned the compressor relay will go off and remain out of the control strategy.

Mercury Plant Controller Installation Guide An “INV Bypass” alarm will be generated. Note if the inverter run signal is not returned within the allotted time in the first instance but is successful in the second, third or fourth attempt (Depending on (P442/443) then any future inverter run tests must still complete all tests. To reinstate the inverter output, once the fault has been rectified, either reset the Plant controller or by using the Override feature force the relay associated to the inverter on.

Mercury Plant Controller Installation Guide External Target Pack Controller To use Sect 1/2 Ext Target (P473/474) instead of Section 1/2 Target Pressure (P-20/40) a status Input must be set to “Run 1/2 N/O or N/C”. When the input is activated the Target Pressure will change from (P-20/40) to (P473/474) When the input is de-activated the Target Pressure will revert back to (P-20/40) Condenser Controller Heat Reclaim must be set to “On” or “On/Rly”.
Mercury Plant Controller Installation Guide Relay Outputs – Configuration Compressor(s)/Loader(s)/Fan(s) relays are assigned using the Stage parameters for a given section. Additional relay outputs for a section will be assigned in the following order once the Stage parameters have been configured.
Mercury Plant Controller Installation Guide Operation (Fuzzy) Once the controller has been set-up and configured, normal operation will resume. If the appropriate Type has been selected the controller will operate using a “fuzzy logic” based control algorithm. The controller will determine the stages to bring on and off using the fuzzy logic rules and adhering to the starts/hr criteria.
Mercury Plant Controller Installation Guide Other operational features Floating Head Pressure When the condenser controller is used in the “Floating Head pressure” mode, the temperature to pressure parameters must be used to profile a pressure curve from the air on temperature probe for the condenser (P414 to P419 and P461 to P466). The value read from the temperature probe is added to a “Condenser Offset” (P422) and then converted to a pressure.
Mercury Plant Controller Installation Guide Invert Relays The operation of the relays can be inverted so that N/C contacts can be used for energisation. This can be done from the configure screen on web page. Choose the relay(s) you wish to invert and set them to on. This process can also be completed from the controller display. Navigate to the menu option rly and select the relay output you wish to invert for example r-05 is relay output 5.
Mercury Plant Controller Installation Guide Viewing Inputs and Outputs Apart from setting up the controller, you can also view the status of the inputs and outputs. 1. From the function menu, select “IO”, press enter 2. You can now scroll through the IO tables as set out below. The tables you view will depend on the controller type configuration.

Mercury Plant Controller Installation Guide Specification Power requirements: Supply Voltage Range: Supply Frequency: Maximum supply current: Class 2 Insulation: 24 Vac ±10% or 24 Vdc ±10% 50 – 60 Hz ±10% <1 Amp Typical supply current: <1.0 Amp No protective Earth is required. A functional earth can be connected if the equipment is located in an electrically noisy environment. Note : The use of centre tapped to earth transformers is not allowed.
Mercury Plant Controller Installation Guide Installation: Mounting on to a DIN rail Clearances: The controller must have 10mm clearance above the top and 15mm clearance from the sides. Clearance at the front and rear is dependent on the site wiring. There is no requirement for forced cooling ventilation Cleaning: Do not wet the controller when cleaning. Clean the front by wiping with a slightly damped lint free cloth.

Mercury Plant Controller Installation Guide Appendix 3 – Supply & Status Input Wiring Appendix three applies to earlier versions of the Plant controller hardware. Connection of the supply voltage and status inputs is important so that the internal bridge rectifier is not damaged. The diagram below shows possible methods of correctly wiring the supply and status inputs. Method 1.
Mercury Plant Controller Installation Guide Appendix 4 – Supply & Status Input Wiring Appendix four applies to the current version of the Plant controller hardware. Method 1. Uses the 24Vac of the transformer supplying the input voltage; which is returned via a switch (or relay) to the status input signal line. No 0V is required at the status connector. Method 2. Uses a 0V return (from the status connector) to the status signal input. Method 3.
